In case you\u2019re just tuning in, I use a lot of mobile apps. Most of them have some feature or functionality that makes them worth recommending. Some are just plain awful. And a few are real keepers\u2014apps that I\u2019ll continue to use on my mobile device long after I test them for this blog.\n\tToday\u2019s post is a look back at my three favorite, recently released iOS apps that I reviewed during the past three months. Check back on Friday for a look at my three favorite Android apps I reviewed during this period.\n\tBento 4 for iPad\n\tBento 4 for iPad is a personal database app from FileMaker, and until August 1 you can buy it for just $5. Even the regular \u00a0cost of $10 is a nice price for a sweet app.\n\tUnlike some other database tablet apps, Bento 4 for iPad is completely self-sufficient; it doesn\u2019t require a desktop companion application to, say, create a new database (or \u201clibrary,\u201d as it\u2019s called in Bento). The app combines drag-and-drop ease with lots of database templates and the ability to download (for free) even more from FileMaker\u2019s Bento template exchange Web page.\n\tThe search function needs bit of work. And I\u2019d like to set my own default theme for all new databases I create. Otherwise, Bento 4 is a delicious productivity app that can help business users cost-justify their iPads.\n\tKlout for iPhone\n\tIf you\u2019re active on social media sites, you\u2019ll want the free Klout for iPhone app.\n\tThe app\u2019s main functions are (a) to constantly inform you of your current Klout score through an app icon badge (see the screen shot below) and push notifications; and (b) to keep you addicted to the practice of constantly checking (and potentially raising) your Klout score. On both counts, the app succeeds.\n\tI reviewed version 1.0 back in May. Since then, the app has been updated. The current edition (version 1.5) now lets you find Twitter users\u2019 Klout scores by searching for their account names. And it now displays all your connected social networks.\n\tA warning, though: Klout is the Krack of social media. Once you start checking your score, there\u2019s no turning back.\n\tLinkedIn for iPad\n\tIt took forever and a decade (or so it seemed), but in late April, LinkedIn finally released an iPad version of its social media app. Even though it doesn\u2019t offer all the features you get using LinkedIn in a browser, the free app was worth the wait.\n\tThe iPad app has a pleasing, Flipboard-inspired interface for browsing status updates and news stories. If you integrate your calendar with the app, you can view the LinkedIn profiles of people with whom you have appointments\u2014a nice touch. You can also see who has viewed your profile, find people you might know, post status updates, and more.\n\tLinkedIn is an essential social-media network for professionals, and the iOS app (also optimized for smaller iPhone and iPod touch screens) will help you make the most of it.
